Avensis T27 2009 2.0D4D ABS Traction control problem

[Ice_mr2turbo]

Good afternoon

i was hoping some of you guys can help me as the toyota dealership here in France cannot

i have a 2009 toyota avensis and it has been with problems for a long time now, when it gets warm 30°C+ outside i have no Aircon, Power steering, ABS, Traction control, Speedometer and check VSV and Park brake system messages, during this winter this has not happened unless i have hit a pothole in the road or we go for long distance driving, 2 hours + driving without stopping and after 10 minutes upto 1 day everything goes back to normal, ive been getting smaller failure aswell when the traction control light and the brake light comes on with the check VSC system message, i have a cheap OBD2 reader which indicated when the smaller failure was on the RH front wheel speed sensor was out, but when the big one is on there is no input from any of the wheel speed sensors. I have replaced the alternator and the RH wheel speed sensor with no change.

i went to the dealership and they did a diagnostics of the car for 5 days without any result and wanted to start to order parts on my expense without being sure it would fix anything, so now i have the toyota techstream software and did a readout of all the codes and was hoping some on here had a clue of what is going on

P0500 =  Vehicle Speed Sensor "A" - This is set because the Engine ECU is loosing a speed signal

C0200 =  Front Speed Sensor RH Circuit - The ABS ECU is loosing signal from the RHF speed sensor

C1201 =  Engine Control System Malfunction ( This is a generic code set by another DTC )

C1330 =  Open in Front Speed Sensor RH

U0129 =  Lost Communication with Brake System Control Module ( This is a generic code set by another DTC )

B2283 =  Vehicle Speed Sensor Malfunction

All of the symptoms and triggers you list suggest you have an open/short circuit in the RHF speed sensor circuit.

A decent auto electrician should be able to check your wiring pretty quick and repair .
